2008 212X - Electrical - port engine not sending info back to dash

[kdcorn]

Hello!
I have an issue where the port engine isn’t sending information to the tachometer, engine stats, etc.

When turning the ignition to on, no beep or flash of lights. The port motor starts just fine. The starboard motor does this just fine, lights, tach,etc.

I took the dash off last night and swapped the wiring from the starboard to port on both the tach and the ignition switch, both work fine with the star board wiring.

I’ve checked for fuses on the ecu, those are fine. Checked the battery hook up and fuses, that appears to be fine.

Where do I locate the wiring harness that sends info back to the dash? How would you trouble shoot this? It worked fine last season, just stopped working.
Thanks! Keith

Check all of the wiring & plugs on the engine itself and just start following it from there.

Check this harness. You open it up to tie in YDS. Sometimes they don't close back up properly.

That makes the most sense because the dealer just ran diagnostics. I did unplug that and check it didn’t fix it. What would I be looking for. Also I saw that for the starboard motor but not the port. From memory that is. I’ll check later. Thanks!!!!

They sometimes hide behind the other harnesses. Open it up and make sure the pin did not get pushed backwards.

Thanks for the follow up

@buckbuck exactly what it was!! Dealer didn’t reconnect the connections. Works fine now, thanks!!
